Can anyone help, i have tried putting back to ECO setting nut it continues to charge both battery and export to grid even tho battery at only 54%.

If it's a single battery, then an 8.2kWh battery can only absorb 2.5kW. Less for 5.2 etc. and (I think) a little more for 9.5kWh. If the solar panels are generating more than the load and the battery can absorb together, then you will export to the grid.

If it isn't that circumstance, then It's something else... 😢

You don't provide any numbers, details of your set up or images of your flows diagram so I'm guessing:

  1. Intermittant solar peaks result in the inverter playing catch up all the time
  2. Solar output is higher than the charge rate setting of your inverter
  3. (if a/c coupled) solar output is higher than the inverter can put into the battery

If you post a lot more information, especially the flows graph for the whole period you are worried about, we might be able to be more specific
